I think I'd be looking for 275N for that type of suit.
Just as an observation - while you're immersed, water doesn't weigh any more when it's in your clothes than it does when it's in the sea. 150N of buoyancy will still provide you with the same upthrust in the water.
However, getting out of the water with lots of wet gear on (or wellies full of water) will certainly add to your overall weight, but a bigger L/J wouldn't help you get out of the water - in fact it can be a hindrance.
The 275N standard is effective when the clothes you are wearing give you more buoyancy (eg survival/immersion suits, or drysuits with trapped air) and change your position in the water - as your lower body floats higher it tends to push your head backwards and the increased buoyancy of a 275N jacket lifts you clear again. Hard work getting out of the water with an inflated 275N jacket - many people find they need to partially deflate it so that they can climb out (but that's easily done)
It's all quite personal, but for what it's worth my own view is that I don't like wetsuits. I find them less comfortable to wear, they can get smelly, and if I'm going into cold water anyway I'd rather be in a drysuit. Drysuits can be uncomfortable too though - even when you spend a grand getting one made to measure with all the latest fancy materials it will still be tight around your neck and once you've decided what to wear underneath for the conditions that day it isn't easy to change. Plain waterproofs or floatation suits are probably more comfortable to wear while you're in the boat but will have their own problems if you end up in the water.
Not easy, but our policy here is - if we're going to be out after dark, or if there's a possibility of ending up in (or being continually lashed by) cold water - it's drysuits. If it's a nice day - it's waterproofs (which may be worn or just brought along). If it's cold but little chance of getting immersed or soaked - it's floatation suits
